A key aspect of Expo Milano 2015 is the array of countries from all over the world that have agreed to interpret the theme: Feeding the Planet, Energy for Life. Food. For food is a vital part of daily life for everyone everywhere. It can bring together people of different cultures and religions, but also implies addressing many challenges. Every participating country has been charged with questioning and offering solutions to the major challenges related to the future of food, and each will provide those answers by drawing upon its own culture and traditions.
Participating Countries have had the opportunity either to build their own exhibition space (the Self-Built Pavilions), or to exhibit inside one of the nine Thematic Clusters. The Expo Milano 2015 exhibition site has thus been transformed into a mosaic of countries committed to creating awareness of a theme that is of critical importance for future generations. Expo Milano 2015: 184 unique days of culture and science, innovation and tradition, sustainability and solidarity where visitors can find over one hundred national cuisines each with their own tastes, aromas, and colors. Below are the countries that have signed up to Expo Milano 2015, and the theme of their exhibit.
